Abstract:

Investigations have shown that perinatal diseases of the prepartum period leads to greater milk productivity in comparison to healthy animals, obtained from cows possessing follicular cysts on ovaries, with uterus inflammation and mastitis. The lowest daily productivity was observed for cows in which ketose was diagnosed, whereas cows with mastitis showed the highest productivity. Occurence of the disorders was correlated with elongation of OMC by 9-109 days in relation to the healthy cows. The occurrence of follicular cysts and inactivity of the ovaries had most adverse influence on the length of OMC, i.e. extending it by 230 and 228 days, respectively. Reproductive indices decreased in all cases of prepartum disorders, however, the differences were not confirmed statistically.
